excellent -

and thank's Dave
next questions :
DEFINE A LIGNE ( to a center of a circle)
I would like to make a ligne ( or a cotation - problem seems the same) from a point to a center of a small circle (4mm diameter).
I have difficulties to find the center of the circle (except by giving its x,y coordonate) wich could be not easy at all.
Is it a better way by using the mouse and clicking ?
AXES
Any way to move temporary the axes to draw a speciel object (or to define another set of axes just the time to draw this object.
DRAWING AXES OF OBJECTS
anyway to do that automatically for circles, rectanle,... (for now I am drawing a line)
MIDDLE
any way to find the middle of something automatically ?
PURCHASING
Did I need to download a new version wich required a new installation
or is it purely a licence key witch update the product status from DEMO to "FULL"
Sorry for all the questions -
The are all here for now and this is my final list.
I am just using Qcad since 2 hours and probably most of my questions are due by my low experience with Qcad.
thanks again for your attention.
